In the present utility model, the air conditioner performs a refrigerating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged. The compressor compresses refrigerant gas in a low-temperature and low-pressure state and discharges refrigerant gas in a high-temperature and high-pressure state. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. Throughout the cycle, the air conditioner may adjust the temperature of the indoor space.
The air conditioner includes an air conditioner outdoor unit, which refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, and an air conditioner indoor unit, which includes an indoor heat exchanger, and an expansion valve may be provided in the outdoor unit or the indoor unit. The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater of a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler of a cooling mode.
Hereinafter, embodiments of the present utility model will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, in an exemplary embodiment of an air conditioner outdoor unit according to the present utility model, the air conditioner outdoor unit includes: a housing, an outdoor heat exchanger, a compressor assembly, a first outlet pipe 1 and a second outlet pipe 2; the outdoor heat exchanger, the compressor assembly, the first outlet pipe 1 and the second outlet pipe 2 are all arranged in the shell, and the shell is used for protecting all equipment in the shell; the outdoor heat exchanger is provided with a refrigerant inlet and a refrigerant outlet, the compressor assembly is provided with an exhaust port and is connected with the refrigerant inlet of the outdoor heat exchanger, the first outlet pipe 1 is communicated with the refrigerant outlet of the outdoor heat exchanger, and the second outlet pipe 2 is communicated with the first outlet pipe 1.
When the air conditioning system is in refrigeration operation, the compressor component discharges high-temperature and high-pressure gaseous refrigerant through the exhaust port of the compressor component, the gaseous refrigerant flows into the outdoor heat exchanger through the refrigerant inlet of the outdoor heat exchanger, and after being cooled by the outdoor heat exchanger, the gaseous refrigerant flows out to the first outlet pipe 1 and the second outlet pipe 2 from the refrigerant outlet of the outdoor heat exchanger, and the refrigerant is still in a high-pressure state at the moment, so that the high-pressure gaseous refrigerant has a larger impact force on the first outlet pipe 1 and the second outlet pipe 2. The necessary buffer design of the first outlet pipe 1 and the second outlet pipe 2 is therefore required. The first outlet pipe 1 comprises a bending part which is not smaller than 150 degrees, the second outlet pipe 2 comprises a bending part which is not smaller than 100 degrees, the first outlet pipe 1 and the second outlet pipe 2 are of large-angle bending design, so that the inner space of a pipeline is smoother, the fluency of the pipeline space is utilized, the buffering capacity of the first outlet pipe 1 and the second outlet pipe 2 to the impact of a high-pressure refrigerant of a system is increased, the outer diameter of the second outlet pipe 2 is larger than that of the first outlet pipe 1, the pipeline space of the second outlet pipe 2 is enlarged, the buffering capacity of the second outlet pipe 2 to the impact of the high-pressure refrigerant of the system is improved by increasing the pipeline space, and the possibility of refrigerant leakage caused by breakage of the first outlet pipe 1 and the second outlet pipe 2 is reduced.
In the prior art, the buffer capacity of the outlet pipe set is generally improved by adding external buffer such as a damping rubber block or adding a fixed mode to the outside, and the buffer capacity of the outlet pipe set is also improved by adding the damping rubber block, wire bundle and the like, but the cost is increased due to the additional material use. Because the outdoor heat exchanger is designed to accommodate both refrigeration and heating uses, the outlet tube bank is designed in the lowest way of the outdoor heat exchanger. In the prior art, in order to avoid refrigerant leakage caused by breakage of the outlet tube set due to impact on the bottom plate of the housing, the outlet tube set is designed in the upper pipeline, so that the design can avoid the outlet tube set from being close to the bottom plate of the housing, reduce the possibility of breakage of the outlet tube set due to impact, but reduce the overall capacity. The utility model adopts the design of bending the outlet pipe group at a large angle and reducing the diameter, solves the problem of cost increase caused by the addition of external buffering, and still adopts the design of the outlet pipe group at the lowest way of the outdoor heat exchanger, and the utility model also adopts the design of bending the outlet pipe group at a large angle and reducing the parallel length of the outlet pipe group and the bottom plate of the shell, thereby solving the problem that the outlet pipe group is easy to collide with the bottom plate of the shell to break on the premise of not affecting the whole capacity.
In some embodiments, as shown in fig. 5, the second outlet pipe 2 has not only an outer diameter larger than the outer diameter of the first outlet pipe 1, but also a wall thickness larger than the wall thickness of the first outlet pipe 1, the outer diameter of the first outlet pipe 1 being 7.0mm, and the wall thickness being 0.7mm; the outer diameter of the second outlet pipe 2 is 9.52mm, and the wall thickness is 1.0mm; the wall thickness of the second outlet pipe 2 is increased compared with that of the first outlet pipe 1, so that the buffer capacity of the second outlet pipe 2 to the impact of the system high-pressure refrigerant is improved, and the second outlet pipe 2 can bear the impact of the system high-pressure refrigerant in the long-time operation process of the whole machine.
In some embodiments, as shown in fig. 2, the first outlet pipe 1 includes a first straight pipe section 11, a first circular arc section 12 and a second straight pipe section 13 connected in sequence, the first straight pipe section 11 is communicated with the refrigerant outlet of the outdoor heat exchanger, and the second straight pipe section 13 is communicated with the second outlet pipe 2; the first arc section 12 enables the inner space of the first outlet pipe 1 to be smooth, and reduces the impact force of the refrigerant on the pipe wall when flowing in the pipeline.
In some embodiments, as shown in fig. 1, when the included angle between the second straight pipe section 13 and the first straight pipe section 11 is smaller than 150 °, the smoothness of the internal space of the pipe of the first outlet pipe 1 is poor, so that the buffering capacity of the impact on the high-pressure refrigerant of the system is reduced, and at this time, the first outlet pipe 1 is easy to break to cause the leakage of the refrigerant. In the utility model, the second straight pipe section 13 inclines from one side far away from the first straight pipe section 11 to one side far away from the bottom of the shell, and the included angle between the second straight pipe section 13 and the first straight pipe section 11 is not smaller than 150 degrees. In some embodiments, the first straight pipe section 11 is close to the bottom end of the inside of the shell, and the first straight pipe section 11 is parallel to the bottom plate of the shell, so that the pipeline parallel to the bottom plate is easier to strike the bottom plate of the shell when the first outlet pipe 1 shakes, in order to reduce the parallel length of the first outlet pipe 1 and the bottom plate of the shell, the projection length of the first outlet pipe 1 on the bottom plate of the shell takes any value between 60 mm and 80mm, so as to ensure that the first outlet pipe 1 can form a bending part of not less than 150 degrees and simultaneously make the length of the first straight pipe section 11 as short as possible, thereby avoiding the longer pipeline to be parallel to the bottom plate of the shell.
In some embodiments, the outdoor unit of the air conditioner further includes a throttling part, the throttling part is disposed in the housing, the throttling part has an inlet and is communicated with the second outlet pipe 2, the refrigerant flowing out of the second outlet pipe 2 enters the throttling part through the inlet of the throttling part, and the throttling part is used for controlling the refrigerant flow of the refrigerant outlet of the outdoor heat exchanger, and the refrigerant is decompressed to be changed into a low-temperature low-pressure liquid refrigerant. The outlet pipe group consisting of the first outlet pipe 1 and the second outlet pipe 2 serves to connect the refrigerant outlet of the outdoor heat exchanger with the inlet of the restriction member.
In some embodiments, as shown in fig. 2, the second outlet pipe 2 comprises a third straight pipe section 21, a second circular arc section 22 and a fourth straight pipe section 23 which are connected in sequence, the third straight pipe section 21 is communicated with the second straight pipe section 13, and the fourth straight pipe section 23 is communicated with the inlet of the throttling component; the second arc section 22 makes the inner space of the second outlet pipe 2 smooth, and reduces the impact force of the refrigerant on the pipe wall when flowing in the pipeline. The third straight pipe section 21 and the second straight pipe section 13 are connected by welding.
In some embodiments, as shown in fig. 5, the second straight pipe section 13 is inserted into and fixed to the third straight pipe section 21, so that the welding joint is firmer, the tightness is better, the defect that the welding joint is easy to crack is overcome, the first outlet pipe 1 and the second outlet pipe 2 are not easy to break, and the service lives of the first outlet pipe 1 and the second outlet pipe 2 are prolonged.
In some embodiments, as shown in fig. 1, the fourth straight pipe section 23 is vertically disposed, the fourth straight pipe section 23 is inclined from a side away from the third straight pipe section 21 to a side away from the bottom of the housing, and an included angle between the fourth straight pipe section 23 and the third straight pipe section 21 is not less than 100 °; considering that the fourth straight pipe section 23 is to be connected with a line leak detection tool to check the tightness of the pipeline, the length of the fourth straight pipe section 23 is at least 40mm.
In some embodiments, the angle between the second straight tube section 13 and the first straight tube section 11 and the angle between the fourth straight tube section 23 and the third straight tube section 21 satisfy the following relationship:
∠1=270°-∠2,100°≤∠1≤120°,150°≤∠2≤170°;
wherein, angle 1 is the angle between the fourth straight pipe section 23 and the third straight pipe section 21, and angle 2 is the angle between the second straight pipe section 13 and the first straight pipe section 11.
The included angle between the second straight pipe section 13 and the first straight pipe section 11 is not less than 150 degrees and not more than 170 degrees, so that the space between the first outlet pipe 1 and the bottom plate of the shell is increased while the pipeline space fluency is increased, and the first outlet pipe 1 is prevented from being broken due to the fact that the first outlet pipe 1 impacts the bottom plate of the shell due to shaking in the long-distance transportation process of the air conditioner.
In some embodiments, when the angle between the second straight tube section 13 and the first straight tube section 11 is determined and the length of the second straight tube section 13 is determined, the length of the third straight tube section 21 determines the height difference between the second circular arc section 22 and the first straight tube section 11, which should be adapted to the height change of the second outlet tube 2 due to shaking, the height between the second circular arc section 22 and the first straight tube section 11 being at least 20mm. Thus, the air conditioner is not easy to strike the bottom plate of the shell when the first outlet pipe 1 and the second outlet pipe 2 shake in the long-distance transportation process, and workers are not easy to strike the bottom plate of the shell when the first outlet pipe 1 and the second outlet pipe 2 are broken to perform leak detection operation, so that refrigerant leakage caused by breakage of the first outlet pipe 1 and the second outlet pipe 2 is reduced.
In some embodiments, as shown in fig. 6 to 10, the third straight pipe section 21 has a reducing section 3, the reducing section 3 is adjacent to the second straight pipe section 13, the outer diameter of the reducing section 3 is larger than the outer diameter of the third straight pipe section 21, the wall thickness of the reducing section 3 is larger than the wall thickness of the third straight pipe section 21, the outer diameter of the reducing section 3 is 12mm, and the wall thickness is 1.2mm. The reducing section 3 is added to the second outlet pipe 2, and the position of the reducing section 3 is arranged at a position close to the welding connection position of the first outlet pipe 1 and the second outlet pipe 2, so that the welding position is reinforced, pipeline embrittlement caused by welding can be avoided, and the possibility of fracture of the welding position is reduced. In addition, the outer diameter of the reducing section 3 is larger than that of the second outlet pipe 2, so that the pipeline space is increased to a certain extent, and the buffer capacity of the second outlet pipe 2 to the impact of the high-pressure refrigerant of the system is further increased.
In some embodiments, the hardness of the first outlet tube 1 is less than the hardness of the second outlet tube 2. The first outlet pipe 1 is used as a transitional connection, and a soft copper pipe, such as a TP2M copper pipe, is selected; the second outlet pipe 2 is used as a supporting pipe, and also needs to be matched and connected with a production line leakage detection tool, and a hard copper pipe, such as a TP2Y copper pipe, is adopted. Wherein TP2 is the English abbreviation of phosphorus deoxidized copper (red copper), the national standard of copper-containing of TP2 is 99.9%, but about 0.015% of phosphorus is added in the smelting process, so that the welding performance of the copper pipe is improved, and therefore, the welding seam and the heat affected zone between the first outlet pipe 1 and the second outlet pipe 2 have good cold crack resistance.
While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
